Question

find the value of m in equation 2m-12=8
​

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

m = 10

Step-by-step explanation:

$\implies$ 2m - 12 = 8

$\implies$ 2m = 8 + 12

Note

If you are bringing a term to LHS or RHS its sign will change. If it is '-' in LHS it when we will bring it to right side its sign will change to '+'.

$\implies$ 2m = 20

$\implies$ m = 20 ÷ 2

$\implies$ m = 10

Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$2m - 12 = 8$

$= > 2m = 8 + 12$

$= > 2m = 20$

$\bold{\pink{= > m = 10}}$

Check:-

$2 \times 10 - 12 = 8$

$= > 20 - 12 = 8$

Concept used :

• When we place value from R.H.S To L.H.S and vice-versa the operational sign of the value gets changed.

More to know :

The term 2m-12=8 is a monomial polynomial as the highest power is 1.
